Answer:
option d) approximately 84%
Explanation:
Data provided in the question:
Mean, m = $92
Standard deviation, s = $13
Now,
we have to calculate percentage of homes will have a monthly utility bill of more than $79 i.e P(X > 79)
also,
P( X > 79) = 1 - P( X < 79)
Z-score for (X = 79 ) = 
Z = 
or
Z = -1
From the standard Z value vs P table, we have
P( Z < -1 ) = 0.1587
Thus,
P( X < 79) = P( Z < -1 ) = 0.1587
therefore,
P(X > 79) = 1 - 0.1587
or
P(X > 79) = 0.8413
or
= 0.8413 × 100%
= 84.13%
Hence,
option d) approximately 84%
Answer:
The Dollar sales break even for the company is $568750, for the north region is $320000 and for the south region is $80000.
Explanation:
1. for the company:
cont margin ration = contribution/sale
= 240000/750000
= 0.32
fixed cost = 182000
dollar sales break even = fixed cost/cont margin ratio
= 182000/0.32
= $568750
2. for the north region:
cont margin ration = contribution/sale
= 120000/600000
= 0.20
fixed cost = 64000
dollar sales break even = fixed cost/cont margin ratio
= 64000/0.20
= $320000
3. for the south region:
cont margin ration = contribution/sale
= 120000/150000
= 0.80
fixed cost = 64000
dollar sales break even = fixed cost/cont margin ratio
= 64000/0.80
= $80000
Therefore, The Dollar sales break even for the company is $568750, for the north region is $320000 and for the south region is $80000.
